tests/acceptance: rename tests acceptance to tests avocado

In the discussion about renaming the `tests/acceptance` [1], the
conclusion was that the folders inside `tests` are related to the
framework running the tests and not directly related to the type of
the tests.

This changes the folder to `tests/avocado` and adjusts the MAKEFILE, the
CI related files and the documentation.
